Title: Semiconductor device
Inventor: MITSUDA YASUKO
IPC: H01L23/50
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent vertical shift of an island and exposure of the island from a resin seal in the case of resin sealing, by forming a cutout on the rear surface of a semiconductor-chip mounting portion such that the cutout are protruded downward by a predetermined height, substantially-vertical to the semiconductor-chip mounting portion, at a specific temperature. SOLUTION: A shape-memory alloy plate 4 having cutouts 5 is attached to the rear surface of an island 1. When the shape-memory alloy plate 4 reaches a predetermined temperature (170 to 180 deg.C), the cutouts 5 protrude downward vertically to the island 1 and a lead 2. When forming a resin seal portion, the cutouts 5 are sealed in a state where they protrude downward vertically to the island 1 and the lead 2, at 170 to 180 deg.C. Thus, the cutouts 5 protruded downward at the sealing temperature (170 to 180 deg.C) become supports to prevent downward inclination of the island 1 and a chip 6.

Title: Optical head
Inventor: ARAI RYUICHIRO
IPC: G02B7/28
Filed: 1986-06-16
Abstract: PURPOSE:To decrease parts of an optical head, to reduce an adjusting part, to make the optical head inexpensive, and to improve the reliability by constituting the optical head so that both servo-signals can be received by a single photodetector in a prism. CONSTITUTION:A luminous flux which has been emitted by a semiconductor laser 1 is condensed by a recording disk 4, reflected thereby and returns in the direction opposite to going, but when it comes to a part of a half mirror 2, it is deflected vertically against the direction of the semiconductor laser 1, reaches a prism 7 and the luminous flux is divided into four, and reaches a photodetector 8. In this case, by a shift of a spot 11 from an objective lens 3 and a track groove 12 on the recording disk 4, intensity of a light spot on the photodetector 8 is varied, therefore, by catching this variation, a tracking servo-signal is obtained. On the other hand, each half of a 0th-order diffracted light 10 of the remaining luminous flux reaches the photodetector 8, and a shape of the light spot on the photodetector 8 is varied in accordance with whether the objective lens 3 and the recording disk 4 are far or near, therefore, by catching this variation, a focusing servo-signal is obtained.

Title: Method for molding inflation film
Inventor: TAKA TOSHIO
IPC: B29C48/10
Filed: 1981-09-04
Abstract: PURPOSE:To obtain an inflation film improved in transparency, by driving a cooling gas jet stream spouted from a jetting ring vertically upon an inflation film with such a strength that the film is deflected but the film can be freed from said deflection afterward. CONSTITUTION:A melted resin leaves an annular outlet 2a of an extruder 1, is permitted to cool so that the viscosity is increased, and is moved up in a cylindrical state. The resulting inflation film (F) in the shape of a cylinder is moved up, is folded by guide plates 4 into a flat shape, and is wound up through haul- off nip rollers 5 and a plurality of guide rollers by a winder 6. In said stage, when the inflation film (F) approaches a frost line f0, and therefore there is still a transparent part in the film before a solid phase appears, a cooling gas is spouted upon said transparent part from a jetting narrow gap 11 of the jetting ring 10 directed vertically toward the film with such a strength that the film is deflected but the film can be recovered afterward. By the cooling gas jet stream, the particular part is quenched, and immediately is supercooled to a temperature of the solidifying point or below, and the film with a feeble frost line (f) remained there is moved up, and thereafter it is allowed to cool at a temperature gradient of natural cooling, and is wound.

IPC: B29C45/76
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To perform injection filling so that a filler having a tendency to orient is not oriented in a specific direction. SOLUTION: A molten resin is injected while the cross-sectional area of a gate 14 is reduced by advancing a needle 20 at an initial stage of injection to generate jetting and, thereafter, the needle 20 is allowed to retreat to increase the cross-sectional area of the gate to perform injection under a condition generating no jetting. When jetting is generated, the flow direction of the molten resin becomes random as a whole and, therefore, the orientation direction of a filler having a tendency to orient becomes random as a whole.

Title: Fixing device of electrophotographic printer
Inventor: NAKAMURA KAZUTO
IPC: G03G15/20
Filed: 1988-06-06
Abstract: PURPOSE:To prevent the generation of wrinkles by providing a couple of rollers which consists of a fixing roller performing thermal fitting and a pressure roller, providing a couple of pressurizing springs which pressurizes and press-contacts one of said couple of rollers to the other roller and mutually and unevenly setting the spring powers of the pressurizing springs constituting the set. CONSTITUTION:The fixing roller 1 is supported by bearings 10 and 11 which are integrated in a frame 2. Brackets 4 and 5 for supporting the pressure roller support the pressure roller on the frame 2 in the way that the pressure roller can recede and advance toward the fixing roller 1, pivotally and turnably support said roller and regulate the relative position and the posture of the pressure roller 3 with respect to the fixing roller 1 by means of their free motion. Then, the spring powers of the pressurizing springs 8 and 9 which energize the right and the left edges of the pressure roller 3 are provided in the way that the spring powers in right and left are different from each other. Therefore regarding nip width W, one edge w1 becomes narrower compared with the other edge w1 and the external form of the nip width becomes closer to a line with respect to an axis direction. Thus, sheets are smoothly fed and the appearance of wrinkles can be prevented.
